One of the fascinating pieces of trivia below is true*, the other is false. Do YOU know which is which?

Jurassic Park (1993)

1) The film cut out many species of dinosaur that were featured in the novel for budgetary and technological reasons. One of these was a small, chicken-sized dinosaur called Procompsognathids, which later made an appearance in The Lost World: Jurassic Park. Dr. Wu explains their reason for having this creature: Dinosaur excrement, he presumes, would have been bio-degradable during the Cenozoic era. However, in the modern day, bacteria have evolved to the point that it is no longer able to break down dinosaur waste, and the larger dinosaurs produce quite a lot of it. “Compys,” as they are called, eat the other dinosaurs’ waste and then excrete it themselves in smaller piles which are more easily broken down by present-day bacteria. The lack of compys in the film may explain the mountain of excrement that Ellie finds.

2) Steven Spielberg’s original intention to bring the dinosaurs to life was to have mules shaved and painted to look reptilian. This plan backfired when the mules trampled actress Carol Channing to death to get at the marshmallows she always kept in her pockets. Channing was replaced in the role of Nedry by Wayne Knight, although her death scene is included in the 2003 Director’s Cut.
